Below, a graphic of all the mass shootings that have occurred in the country since the Tree of Life synagogue attack shows that at least 79 people have been shot from Watertown, New York, to Los Angeles.

All data has been compiled by the Gun Violence Archive, which defines a mass shooting as an incident in which four or more victims are shot.

CORRECTION (Nov. 9, 2018, 2 p.m. ET): An earlier version of this article misstated the number of people killed in mass shootings since Oct. 27. There were 79 people who were shot, not 79 who were killed. (Twenty-three people were killed, including the 13 in Thousand Oaks this week.) In addition, the article misstated the number of mass shootings in that time period. There were 12, not 11.
